I'll read up on named and give it a shot. But it seems as though the
connection is made without probs to the internet www server. Then it
takes a long time to actually get packets flowing to my LAN client. I
would think that DNS isn't too much the culprit because the tcp connection
is established. So from there DNS lookups wouldn't be all that common
since my NetNSD box already has the IP of the www host. So maybe moving
the packets from the real internet IP over to a LAN IP is killing
it......just doing a straight ftp to the NetBsd box from the internet was
going at about 445 kbps last night. But jumping to a client show more like
2 kbps. It couldn;t load all of CNN's homepage before the in the 5-10
minutes I waited.
hmm...
Thanks
